Challenge: Simultaneous machine translation (SiMT) aims to yield a partial translation with a monotonically growing source-side context.
Approach: They propose a training approach that encourages consistent context usage between training and inference by optimizing translation quality and latency as bi-objectives and exposing the predictions to the model during the training.
Outcome: The proposed system outperforms existing SiMT systems with context inconsistency for the first time.

Revisiting Context Choices for Context-aware Machine Translation (2024.lrec-main)

Challenge: Recent work has cast doubt on whether context-aware machine translation models learn useful signals from context or are improvements in automatic evaluation metrics just a side-effect.
Approach: They propose to use separate encoders for source sentence and context as multiple sources for one target sentence to train context-aware machine translation models.
Outcome: The proposed model improves translation quality even with empty lines as context, but the correct context improves it and random out-of-domain context degrades it.
Self-Modifying State Modeling for Simultaneous Machine Translation (2024.acl-long)

Copied to clipboard

Challenge: Existing methods for simultaneous machine translation fail to optimize the policy . existing methods require building a decision path to learn the policy, but they cannot explore all potential paths .

Outcome: The proposed model outperforms strong baselines and allows offline models to acquire SiMT ability with fine-tuning.
